It's NTR bait. There's nothing deep or complex about being into that vs. people being grossed out over a fluff series rugpull turning into Boy's Abyss.
I hate April Fools on this site. Last year they put up a chapter for Meika-san with a mistranslation that made it seem like a big dramatic new arc was starting, instead it was supposed to be the big story culmination and then the series ended two chapters later.
Thanks for picking this up. It's one of the best books I've read that can balance robo-waifu fluff with deep discussions of the human condition. The best kind of sci-fi.
I was really hoping there would be some sign of Hina at the wedding to indicate Yuuki made things right with her, but nope, she just got her dreams of friendship completely crushed and then kicked to the curb. Damn.
There's literally nothing good about this manga: all the characters are terrible people, it's depressing as fuck, and yet I can't stop reading it because I need to see how this car crash ends.
